This adds reporting of an error in CFE for ?.length in constant expressions and improves the message for the analyzer in the same case. The error in the analyzer was previously the invalid claim that
The property 'length' can't be accessed on the type 'Null' in a constant expression.

FE/analyzer shared code
This package contains logic that is shared between the front_end and analyzer packages. It is intended solely to facilitate development of the Dart SDK, and is not intended for use by end users. In particular, this package has no public API, so no guarantee is made of compatibility between one version of the package and the next.
End users should consider using the analyzer package to analyze Dart source code.
